The chapter is a noble piece of patriotism--one of the noblest of a race who, although for the greater part of their history without a fatherland, have contributed more brilliantly than perhaps any other to the literature of patriotism, and that simply because, as Isaiah here illustrates, patriotism was to their prophets identical with religious privilege and responsibility. Isaiah carries this to its bitter end. Other patriots have wept to sing their country's woes; Isaiah's burden is his people's guilt. To others an invasion of their fatherland by its enemies has been the motive to rouse by song or speech their countrymen to repel it. Isaiah also hears the tramp of the invader; but to him is permitted no ardour of defence, and his message to his countrymen is that they must succumb, for the invasion is irresistible and of the very judgement of God. How much it cost the prophet to deliver such a message we may see from those few verses of it in which his heart is not altogether silenced by his conscience. The sweet description of Judah as a vineyard, and the touching accents that break through the roll of denunciation with such phrases as _My people are gone away into captivity unawares_, tell us how the prophet's love of country is struggling with his duty to a righteous God. The course of feeling throughout the prophecy is very striking. The tenderness of the opening lyric seems ready to flow into gentle pleading with the whole people. But as the prophet turns to particular classes and their sins his mood changes to indignation, the voice settles down to judgement; till when it issues upon that clear statement of the coming of the Northern hosts every trace of emotion has left it, and the sentences ring out as unfaltering as the tramp of the armies they describe.
Isaiah adopts the resource of every misunderstood and unpopular teacher, and seeks to turn the flank of his people's prejudices by an attack in parable on their sympathies. Did they stubbornly believe it impossible for God to abandon a State He had so long and so carefully fostered? Let them judge from an analogous case in which they were all experts. In a picture of great beauty Isaiah describes a vineyard upon one of the sunny promontories visible from Jerusalem. Every care had been given it of which an experienced vine-dresser could think, but it brought forth only wild grapes. The vine-dresser himself is introduced, and appeals to the men of Judah and Jerusalem to judge between him and his vineyard. He gets their assent that all had been done which could be done, and fortified with that resolves to abandon the vineyard. _I will lay it waste; it shall not be pruned nor digged, but there shall come up briers and thorns._ Then the stratagem comes out, the speaker drops the tones of a human cultivator, and in the omnipotence of the Lord of heaven he is heard to say, _I will also command the clouds that they rain no rain upon it_. This diversion upon their sympathies having succeeded, the prophet scarcely needs to charge the people's prejudices in face. His point has been evidently carried. _For the vineyard of Jehovah of hosts is the house of Israel, and the men of Judah his pleasant plant; and He looked for judgement, but behold oppression, for righteousness, but behold a cry._
